Awesome! Now anyone using the Google Toolbar can leave comments for others to see about your webpages through Google Sidewiki.

Luckily you can (through Google Webmaster Tools) create a webmaster entry that will appear on top, but this is a challenging new feature for anyone (like me) who is trying to get a handle on existing webpages that you know are not designed to their full effectiveness. Now users can comment on those type of issues.

This is also going to make it challenging to know the reason why your landing pages are not converting – is it because of the landing page itself, or the SideWiki text?

So much for the line between a website and a blog. Now even static content can have commenting going on whether or not you as a webmaster intended for that to happen.

I can’t find anything within the documentation that makes it easy for you as a webmaster to sign up for a feed of updates on SideWiki comments on pages you own – let me know if you figure out how that can happen. Otherwise I’m not sure (as a manager of multiple websites) how you stay on top of something like this…

a graph with the search volume, indicating interest over time (GMT) for your terms, plotted on a scale from 0 to 100; the totals are indicated next to bars by the search terms (read more about how we scale and normalize the data)

lists of the top searches and top rising searches

It only shows terms with a significant amount of search volume, and of course it’s only Google search data, but worth looking at as your expanding your keyword list. Check out Google’s newest beta tool.
